HEDDLE STOP MOTIOI I: FOR LOOMS.

Application filed July 18, 1922. Serial 110. 575,781.

which will act also in the capacity of a stop motion for looms.

Another object of the invention is to provide a heddle wherein the yarnmay be threaded into the eye without disconnecting the heddle 'orwithout using an instrument,

the heddle being formed with means sup-- ported by the yarn acting as astop motion attachment.

A still further object, more specifically, is to provide a heddle andstop loom wherein a pair of heddle strips are used for the combinedpurpose of holding the yarn and guiding a stop strip held inplace bytheyarn when the parts are in o erative position and permitted to dropfor c osing an electric circuit when any yarn is broken.

In the accompanying drawing- Figure 1 is a fragmentary elevation of aheddle frame with a pair of heddles ar-' ranged therein disclosing anembodiment of the invention, the same being shown in connection with astop motion circuit.

Figure 2 is a sectional view through Figure 1 approximately on line 22.

Figure 3 is a plan view of the two heddle strips and stop motion stripshown in Figure 1 by numerals, 11 indicates a heddle frame of anydesired or preferred kind provided with the usual top and bottom bars 12and 13 and the usual end bars 14. The heddle supports 15 and 16 are ofthe usual type which receive the slotted ends of the strips 17 and 18which make up. the heddle 19. Associated with these, strips and arrangedtherebetween is a stop motion strip 20 which is a flat strip preferablyof'the same width as the strips 17 and 18 and also preferably slightlylonger so that the upper end may be provided with the usual slot 22 foraccommodating the support 15. It will be noted that-the slot 22'is'longer than the support 15'is wide which is also true of the lower slot23 so that when not supported the strip 20 may drop down and the point24 engage the contact bar 25. This contact bar is provided with aninsulating covering 26 designed tocover the entire bar except the upperpart, said barbeing also insulated from the frame 11 and connected bywire 27 to a suitable source of current 28. The heddle frame 11 isconnected by wire 29 to an alarm 30 which is shown as a bell and also bya wire 31 to a switch or other. mechanism used for throwing off thepower to the loom so as to stop the same;

The wire 32 also extendsto the same switch,

as wire 31 and a suitable connecting wire 33 connects wire 32 to thebell30.

By this construction and arrangement, whenever the stop motion strip 20is in its elevated position, no current will flow either to themechanism for throwin out the switch or other power nor to the bell 30but in case one of the yarns 34 should break, the particular strip 20supported thereby would drop down under the action of gravity until thepoint 24 engages the contact bar 25. As one side of the bell 30 .isgrounded on the frame 11, this would cause a closing of the circuit andthe bell immediately begin to ring and the mechanism for shutting offthe power would be operated, said mechanism being of any desired orusual.

ty e. v 7 lirom Figure 3 it will be observed that the heddle sections orstrips 17 and 18 are rovided with notches 35 and 36 merging mtp eyeopenings 37 and 38, which openings register and form an eye for the yarn34 when the parts are in operative position. The strip 20 is providedwith an inclined slot 39 whereby this strip may rest on the yarn 34' andbe supported thereby normally but permitted to drop by gravity, when theyarn breaks. The various strips 17, 18 and 20 are,

all flexible and are preferably made out of flexible steel strips sothat a yarn may be easily placed into he eyes by bowing these strips 1nopposite directions and forcing the yarn through by hand.

What I claim is v 1. A heddle and stop motion for looms, comprising aheddle frame, a pair of strips forming a heddle carried by said frame, acomparatively large opening 21 as well as ;ings, a third strip having anopening for.

receiving the same yarn that extends through the openings of the heddle,said third strip being supported by said yarn,.a contact bar positionedto engage said third strip when the same is. moved downwardly apredetermined distance, and means connected with said contact bar forshutting off 7 the power of the loom.

2. A combined heddle and stop motion, comprising a heddle frame, aheddle formed of two strips provided with an eye for receiving the yarn,a stop motion 'striparranged between the first mentioned strips providedwith means acting as an eye for receiving said yarn, said stop motionstrip being supported by said yarn, said stop motion strip having anelongated opening near the (top, a contact bar extending through saidopening, and electrically operated means connected with said bar and theheddle for giving a signal when the stop mo tion strip moves downwardlyunder the action of gravity a predetermined distance.

3. In a combined heddle and stop motion for looms, a heddle frame, aheddle formed of two strips positioned side by side, carried by saidframe, and a stop motion strip arranged between the first mentionedstrips.

4:. In a combined heddle and stop inotion,

-a heddle frame, a heddle structure formed of two strips having meanspresenting an eye for a yarn, a stop strip arranged be tween said heddlestrips formed with a notch for receiving said yarn so that the stopstrip may be supported by a yarn, said stop strip having an elongatedopening at one end, a

contact bar extending through said opening whereby when said yarnbreaks, the stop strip may fall and engage said contact bar,

and an electric circuit adapted to be closed by said stop strip when thesame engages said contact bar.

5.,In a combined heddle and stop for openings, and an alarm striparranged between the first mentioned strips, said alarm strip having anopening for receiving saidyarnwhereby it is supported;

7. A heddle-detector, comprising a pair of thin fiat strips havingregistering yarn receiving openings, each ofsaid openings being formedwith a notch extending inwardly from one edge of the respective stripsand merging into an enlargement, the enlargement of the opening of onestrip registering with the enlargement of the opening of the otherstrip, with the remaining parts of the respective notches out ofalignment.
